BMK CLIMBING BRACKETS

 

4.3.

 

CURVED AND POLYGONAL WALLS 

For solutions of curved and polygonal walls, the Fixed Head (1991410) is replaced by a special head with a 

particular angle for each application. 

                  

 

 

4.4.

 

ANCHORAGE SOLUTIONS 

The anchors are the tie members of the climbing bracket to the wall. 
It is of utmost importance to embed the anchors into the concrete as indicated in the assembly drawings in order 

to correctly transmit the loads from the structure to the concrete. The correct transmission of the anchor reactions 
to the concrete is responsibility of the customer. Only genuine components of ULMA may be used. 

Depending on the reactions in the anchors, DW20 or DW15 anchorages are used. 

 

 

 

 

 

 
 

 

 
 
 

 
 

 
 

Change of Fixed Head (1991410) by 
special head for inclined wall 

Do not weld anchorage components because of the risk of fractures.
